To me, it sounds like you know what you want to do, but would like some support in that decision and to be told that it will all be okay if you follow through with that decision. So, I want you to know that no matter which way you decide to go, it's going to be okay -- you are going to be okay. To have had your son move out and choose to live with his father over your household because it was too much for him definitely speaks loudly to the environment in which you are and have been living in. Getting a PTSD diagnosis is definitely a good thing in that you can work with that... but the diagnosis itself it not necessarily going to change anything, unless your husband is able to take the diagnosis and really work on improving things for himself... and that is just so much easier said than done. This is just the beginning of what will be a very long road of recovery and learning to cope with his symptoms. As you've already been experiencing for the past 8 years of marriage with him, it's a wild, crazy and emotional roller coaster and just because a doctor was able to diagnosis it as PTSD doesn't mean that the roller coaster now ends. I'm glad you are reading about it and encourage you to read and research more, continue working with your therapist because there are definitely things that you can do on your end to help in reducing the chance of triggering your husband, learning how to communicate effectively, making sure you are taking care of yourself in the process, learning about what he goes through and experiences, etc, etc. Knowledge is power -- but if I were to be 100% truthful with you -- even though you could do everything possible, the change in your dynamic is 50% him and therefore he ALSO has to put forth his best efforts day in and day out to manage his PTSD in order for there to be real change.
If you are already at the point where you feel that you need to take a step back from the relationship right now, then you make the decision that is best for you and your children in this moment. Holding out hope that things could change -- well, you could be waiting a very long time. I'm not saying give up -- I'm saying that if you feel strongly enough that you need some space right now, that it's okay to take that space so you can figure out the things you need to figure out for you and your children. This will also allow your husband some time as well -- it' not going to be easy -- this could be really difficult for him to take so in my opinion, it's important to remind him that you are making this decision to hurt him, but to help in the healing process of ALL of the members of your family. If you haven't completely lost hope in your marriage, then be truthful and honest with him about that -- that you WANT to see things improve and that you still care for him and love him and that you will be there for him but that you just need a little time and space to help in changing your dynamic to be a healthier one.
I wish you and your family the best as you move forward.
